highly porous MXene electrodes that are resistant to nanosheet restacking and deliver high
electroadsorption capacity for capacitive deionization (CDI) of saline water. In CDI cells
constructed with aerogel-like Ti 3 C 2 T x MXene electrodes, an adsorption capacity of 118
mg/cm 3 (45 mg/g) was achieved in a 10,000 mg/L salt solution, more than one order of
magnitude greater than carbon-based electrode materials.
